Embodiment 1

[0027] The aluminum alloy plate is selected as the base material, and its composition is shown in Table 1. In order to improve the absorption of laser energy on the surface of the aluminum alloy, the surface of the sample was polished to remove the oxide film before laser cladding. The cladding material is a spherical powder with a particle diameter of 50-100 microns, and the main component is Fe. The specific components are shown in Table 1.

[0028] Equipment includes: YLS-3000 fiber laser (Germany IPG company); PERCITEC YC52 transmission laser cladding head (Germany Precitec company); FHPF-10 coaxial powder feeder (Feihong laser).

[0029] The range of powder feeding particles is 200~400 mesh; KUKA-KR30 manipulator, the repeat positioning accuracy is less than 0.06mm; the powder gathering range is 0.7~3mm, and the powder spraying distance is 12~14mm.

Abstract

An aluminum alloy laser single-pass cladding process method, relating to an aluminum alloy cladding process method, the method uses nickel-based metal powder combined with 3000 watt fiber laser equipment, and then uses a KUKA robot as an actuator, and adopts manual programming or automatic programming The precise trajectory interpolation motion is carried out through the contour control method, combined with the precise powder feeding volume control of the four-axis coaxial powder feeder, by adjusting the powder feeding volume, feed speed, laser power, nitrogen shielding gas flow rate, lap joint Rate parameters, using optimized and reasonable process parameters to perform single-pass laser cladding repair on two-dimensional or three-dimensional complex or simple worn and damaged surfaces of parts or molds; the repaired parts or molds quickly meet the performance requirements for reuse, making the originally scrapped Parts or molds perform better than before.

Description

technical field [0001] The invention relates to an aluminum alloy cladding process, in particular to an aluminum alloy laser single-pass cladding process. Background technique [0002] Optical cladding technology has been widely used in the industries of developed countries such as Japan and the United States, especially in the fields of automobiles and aerospace, and mature industrial production lines have been established. [0003] It has a series of advantages such as low density, high specific strength, good corrosion resistance and formability, and is widely used in manufacturing industries such as automobiles, ships, and aerospace. However, aluminum alloys also have many problems, such as low surface hardness and poor wear resistance. Its scope of application is largely limited. Laser cladding on the surface of aluminum alloy is an effective method to improve the performance of aluminum alloy. It is characterized by extremely fast cooling rate, fine structure of clad...
